TC74VHC9126P/FT/FK 5-bit Universal Schmitt Buffer with 3-State Outputs
The TC74VHC9125/9126 are an ultra-high-speed 5-bit Schmitt
buffer fabricated using silicon-gate CMOS technology. The
TC74VHC9125/9126 combines low power consumption of CMOS
with Schottky TTL speeds.
Y1 to Y4 outputs can be put in the high-impedance state by
placing a logic HIGH on the Enable ( G ) input. The CONT input
determines the logical inversion of data.A logic LOW on the
CONT input configures the TC74VHC9125/9126 as an inverter; a
logic HIGH on the CONT input configures the
TC74VHC9125/9126 as a buffer.
TC74VHC9125 Y5 output is an inverting type, and the
TC74VHC9126 Y5 output is a non-inverting type.
All the inputs have hysteresis between the positive-going and
negative-going thresholds. Thus the TC74VHC9125/9126 are
capable of squaring up transitions of slowly changing input
signals and provides an improved noise immunity.
Additionally, all the inputs have a newly developed protection
circuit without a diode returned to V_CC. This enables the inputs
to be tolerant of up to 5 volts even when power supply is down.
The input power-down protection capability makes the
TC74VHC9125/9126 ideal for a wide range of applications, such
as interfacing between different voltages, voltage translation
from 5 V to 3 V and battery back-up circuits.
